First of all, I want to note, that I've checked out this thread:
PC specs: https://uk.pcpartpicker.com/list/thhsQV
Please note, that I got the stock cooler for the CPU
I've also clocked CPU to 3.3GHz, running 3.29GHz
Not sure I've seen it run much higher than 40% CPU usage, with the exception of benchmarks.
Warframe:
Although disabling HPET worked, to some extent; I'm still never reaching in 80%+ GPU usage, when in-game.
(usually hovers on 40-60% gpu usage, with around 1,2gb vram usage.)
There are two exceptions: The first is login screen, where I get 500~ish FPS, 99%gpu usage;
and similarly, the second, is when I'm in loading screen, and someone else is hosting, I get up to 700 FPS,99% gpu usage.
(Guessing, that this is because, some sort of limiter is off, and/or lowered settings/less to render.)
Dark souls 3, is probably the one that's doing the, worst on my setup, since it hitches quite often, and quite badly...
Also even if it says I'm 58-60 fps, it's not consistently timed; hence, even if the fps is correct, it's mini hitches most of the time.
(Say 45fps in the first half second, then 15fps then the last half, just as an example; I've not tested, the consistency, because I can see it's not consistent.)
What I've tried:
Overclocking GPU/CPU (individually & together)
Testing to see, if GPU auto throttles due to low wattage/not enough power; it doesn't as it works on 99% some games,
that are more HW intensive (Tested CoD AW + filling memory settings, no problem, runs at 99% quite stable.)
Nvidia Power settings, fiddling around with sync, & other settings: No difference.
Disabled, and I deleted HPET (Enabled using more than 40% of GPU.)
(I think, I deleted it, said so in Powershell window.)
Drivers should be up to date; if not, the pc is just 2-3 months old, got it the 28/29th of July, I think it was.
(Installed all, of the newest drivers, when I got it; so if they're not the newest, they're relatively new.)
Everything is connected properly, in the right slots.
Tried other games, only other I've found any similar problems with, is League of Legends,
where FPS starts out 220-250, then drops to 100-120 after a few minutes.
(GPU usage start out at 30-35%, then drops down to 15-25%)
Tried benchmarking, GPU uses 99%, and got good results.
Using genuine Win10 Pro, 64bit
(Only because win7 doesn't support M.2 NMVe drives, and being used to windows +
I've heard Linux has just gotten Dx9/Dx11, from a Linux user; can't remember which.)
Tested Dark Souls 3, on max settings, averaging out on 45% gpu usage, topped on 55%, about 3,1gb vram usage.
I'm also getting a lot of hitches, ruining gameplay; considering dodging & similar, becoming hard to time.
(Also aware of the 60 FPS limit of the game, although this is still no excuse for the hitching.)
Looked for VT-d settings in BIOS, did not find any
Tested Nier: Automata, got 80%+ gpu usage, around 4gb vram usage, occasional fps drop, on maxed settings.
(Usually 90%+ gpu usage)
Overwatch works like a charm, even on maxed settings, getting 90%+ gpu usage, & 150-180 frames on "epic" settings, w/ 100% texture scaling.
The tests, that I ran, to check GPU usage percentages, I ran on default clock speeds
(1506MHz GPU clock, 2002MHz mem clock.)
(Says 1835MHz, on core clock, under sensors tab, in GPU-z)
Have yet, to see my GPU, go over 65 Celsius, and my CPU over 68-70 Celsius
What I haven't tested:
Underclocking PC
Disabling VT-d (Since I couldn't find it anywhere.)
Disconnecting extra monitors, via plugging out cables.
(Although secondary screen wasn't plugged in for 2-3 weeks; before getting extra cable for, so ran without it for a while.)
Secondary screen for browser + monitoring GPU/CPU, 3rd screen is TV.
(For viewing stuff/playing with controller; is usually off.)
All 3 monitors are 60Hz, but some games have other bonuses by running higher FPS.
Random picture, of small ds3 hitch + HW monitoring. (Had far worse hitches, but hard catching them on print screen.)
Edit: Forgot to add cpu temp into HW monitor.
